Foxboro P0914ZM Identification Module

Fieldbus Communication

The fieldbus communication module or control processor is connected to the

redundant 2 Mbps modular fieldbus used by the FBM.

The Compact FBM242 accepts communications from either path (A or B) of

the redundant 2 Mbps fieldbus

– if one of the paths fails or is not in operation, the FBM will not accept

communications from the other path.

If one of the paths fails or is shut down at the system level, the module will

continue to communicate over the active path.

Current Limit

Field power supplies used for contacts or solid state switches are current limited.

Terminal Assembly (TA)

Field I/O signals are connected to the FBM subsystem via DIN rail mounted TAs.

Visual indicators

Light-emitting diodes (LEDs) on the front of the module provide a visual indication

of the module’s operating status and the discrete status of each output point.

Features

Key features of the 200 Series Base Plate are listed below:

 for FBM-enabled baseplates:

– 2. 4. and 8 module positions combined with vertical and horizontal mounting

– Field connectable I/O termination assemblies, redundant adapters, and modules

Identifiers for each module

– DIP switches for identification of specific module backplanes

– Additional 200 series baseboards can be added without removing the

system from service (redundant bus required)

 supports FCP280/FCP270. FDC280. and FCM100Et baseboards:

– Connection for optional GPS time strobe.

All non-FDC280 module time strobe connections require a splitter/splitter.

direct connections are supported on the FDC280 baseboard.

 All baseboards are supported except the FDC280 baseboard (RH101KF):

– Connection to 2 Mbps modular fieldbus for standard fieldbus modules or 268 Kbps

fieldbus for 100 series FBMs

– Splitter/terminal modules for A/B fieldbuses

– Backwards compatible with existing I/O subsystems, allowing for future expansion

No additional interface hardware required

 Primary and secondary 24 VDC power supplies and communication connections

 Dedicated keying position for individual CP-type modules (e.g. FCP280. FDC280

or FCM/FBM),

depending on the substrate type
